Improvement in pumps



UNITED STATESA PATENT OFFICE,

MARTIN V. ZIMMERMAN AND JOHN ZIMMERMAN, OF EARL TOWNSHIP, LANCASTER COUNTY, PENNSYLVANIA.

IMPROVEMENT" IN PUMPS.

Specification forming part of Letters Patent No. 42,617, dated May 3,1864.

To aZZ whom it may concern:

Be it known that we, MARTIN W. ZIIWLIER- MAN and JOHN ZIMMERu/IN, of Earl township, in the county of Lancaster and State of Pennsylvania, have invented a new and simplied Improvement in Operating Ordinary Lifting-Pumps; and we do hereby declare that the following is a full and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

The nature of our invention consists in simplit'ying the same by using but one wire instead of two.

Figure l illustrates the arrangement of the rocking shafts, arms, and single wire, operated by the crank on the water-wheel at any distance from the pump, and any number ot' intermediate posts,F, and spring-supports s may be employed. Fig. 2 shaws the piston or pump rod a: between screwburs v o on the screw y, held beneath the rocking shaft B for the purpose of regulating the stroke of the piston or pump rod. Fig. 3 illustrates the mode of forming branch posts, if desired.

The drawings clearly show the construction of our invention, and will enable others skilled in the art to make and use the same.

The common Water-wheel M, with a crank, N, and connecting-rod, O, attached to the arm J, operates the vibratingmotion of the rocker-shaft H, with its perpendieulararm I, to which the wire W is secured. This rockershai't is held between two upright posts, G G. There is also a brace, K, connecting the arms I J. The wire W is supported at intervals in a notch made in the topot' a exible lath or strip, S, of iron, secured to the top of a post, F, any number of which maybe employed, accordingly as the distance is more or less great between the pump A and water-wheel M. At any point on the line a rocking shaft, Fig. 3, may be set for the purpose of starting out adiverging line to another pump or adopting a different course in the line of the wire, the arms Q Q so placed in relation to the vibratin g upright R,held as shown,as to indicate the desired angle of departure or object aimed at. The rockerblock B, with its arms O C D, sets over the top of the pump A, held in side supports. Beneath this block is the regulating-screw y, by which the stroke of the pump can be decreased or diminished in proportion as the piston a: or pump-rod is brought nearer or is farther removed from the pivot or center of the fulcrum of the vibrating block B, thereby regulating the discharge of water at pleasure or arresting the same entirely. The projecting arm e may also be employed in like manner as a common pump-handle. To the opposite arm, c,a rod, E, may be attached and employed in stamping or turning a crank, j'. To thisarm there is ball or weight, L, which aids in the requisite motion, and when but one pump is operated upon a counterpoise, L, is also appended to the arm J, connected with the crank N by the rod O. This latter weight or counterpoise is not needed on J When two pumps are operated, as it can then be applied to the projecting arm c of such other pump as a counterpoise.

We are aware that the waterwheel and crank are not new, and that they are also elnployed for operating pumps in connection with two parallel wires, either horizontally or vertically applied to pivoted arms or crossarms. Such we do not claim. We save the expense of one-half of the Wire by using but as ingle line instead of two, aided by a counterpoise or weigh ted arm.

What we claim as our invention, and desire to secure by Letters Patent, is-

The use ofa single wire in combination with the regulating-screw y, burs 'v o, rocker-shafts and arms B HR, weights L, operated by a Water-Wheel and crank, in the manner and for the purpose specified and shown.
